907-GBES Media Converter

The 907-GBES Gigabit Ethernet (GbE) Switch Media Converter is a 4-port switched version of the popular PC/104 form-factor cards. Compatible with 10/100/1000 Mbps devices, the switched interface card can manage traffic from multiple gigabit devices or allow simultaneous 100 Mbps Ethernet links to be transferred optically with bandwidth to spare.

The 907-GBES may be used as a standalone card or optically integrated into a 907 system stack via CWDM modules. Optical power budgets are typically 20 - 26 dB over 10 km of singlemode fiber. Enhanced diagnostics are provided by on-board LEDs and through a dedicated Ethernet link when used with diagnostics card (907-DIAG-E) and corresponding graphical user interface (GUI) software.


  • Ethernet switch with four 10/100/1000 Mbps RJ-45 copper ports and one 1.25 Gbaud optical port
  • Wavelength selectable/interchangeable SFP transceivers
  • Rugged design for harsh environment, including 6000 psi pressure tolerant version
  • Compatible with 907-DIAG-E diagnostic card and Graphic User Interface (GUI) software


  • Provides multi-port Ethernet to optical conversion with a reliable small form-factor card
  • Configures RJ-45 ports automatically to link with connected Ethernet device
  • Supports a wide range of optical options, including CWDM wavelengths
  • Simplifies troubleshooting with advanced diagnostics
